PTFE Teflon Is a very versatile, flexible fluoropolymer.Polytetrafluoroethylene This is the English name of the expanded body.Poly- means 'polymerization'; tetra- is an affix of 'four' in English; fluoro- is a chemical element 'fluorine'; ethylene- is a polymer material that we are all familiar with: ethylene.Therefore, the scientific name is also called polytetrafluoroethylene.Take its four capital letters as shorthand:PTFE.

PTFEThe mechanical strength is slightly lower than other plastics, but by adding composite materials such as glass fiber, carbon fiber or copper fiber, its mechanical properties can be effectively strengthened, and it can perform the best function in various environments.PTFE has excellent temperature resistance, chemical resistance, and drug resistance. Its melting point is 327°C, and it can be used at extremely low temperatures down to minus 170°C. It is an excellent heat-resistant material.It will not react to concentrated sulfuric acid or boiled aqua regia. In various extremely harsh environments, PTFE and its families will be excellent application materials.

PTFE (Teflon), ECTFE (Halat), ETFE (Teflon), FEP (Teflon),PFA (Teflon), PVDF and modified PTFE (EPTFE), like partially fluorinated or perfluorinated polymer materials, can be processed by thermoplastic molding. They are very good for almost all organic and inorganic compounds, whether they are acidic or alkaline. high tolerance.These materials show generally durable resistance to acids, alkaline solvents and chlorides.A class of thermoplastic resins that contain fluorine atoms in their molecular structure.It also shows excellent resistance to mechanical damage in terms of wear resistance, impact and toughness.

Teflon PTFEMain features: anti-adhesion; chemical resistance; wide service temperature (-200℃~+260℃); low coefficient of friction; superior surface smoothness; superior durability; excellent electrical properties; UV resistance

Teflon is not wetted by water and oil, and can be used as a non-stick coating for pots and cookware; while Teflon is resistant to acids, alkalis, and various organic solvents, it is used in the chemical industry. Loading with aggressive chemicals provides a stable, safe choice.The advantages of Teflon's low coefficient of friction can also be used as a lubricant for connecting surfaces to reduce friction and wear.

at presentTeflonIt is widely used in food industry, semiconductor, chemical industry, machinery, construction, medical and other industries. The characteristics and application of each industry type are slightly different, but it is an excellent material with stability, safety and high durability.
